Gloria Marshall attended a remembrance day on 16 May 2005

Steve Mohabir and Gloria Marshall are visiting Goodwood Motor Circuit on Monday, where drivers aged from 17 to 25 are educated on accident prevention.

Mr Mohabir was the only survivor of the crash in May 2004, which killed his two-year-old son Marcus.

Eight people lost their lives including Mrs Marshall's son and daughter.

Katherine Sharpe, 18, and her 20-year-old brother Aaron - from Crawley, West Sussex - were passengers in a BMW which crashed through the central reservation into the path of a Land Rover Freelander.

They and three other teenagers in the car were all killed.

Mrs Marshall's son, Aaron Sharpe, was one of the victims in the BMW

Mr Mohabir was in the Freelander with his son, and two other people who also died.

The accident happened on the dual carriageway A23 at Pyecombe, near Brighton.

At an inquest in April a coroner ruled that the BMW driver was probably going "well above the speed limit".

Mrs Marshall, from Crawley, and Mr Mohabir, of Godalming, Surrey, have already been campaigning about the dangers of speeding with the Sussex Safety Camera Partnership.

The day-long skills course at Goodwood, near Chichester, is being run by West Sussex County Council and the University of Southampton.
